The Adams County Health Department recently collected samples of mosquitoes in Adams County that have tested positive for West Nile Virus. The Adams County Health Department urges county residents to continue to protect themselves from diseases carried by mosquitoes such as West Nile Virus and St. Louis Encephalitis through the rest of mosquito season. There have been 5 confirmed cases of human West Nile infection in the state. The Indiana Department of Health has identified groups of mosquitoes carrying the virus in surrounding areas as well, including Allen, Wells and Jay Counties.
Mosquitoes will remain active as warm weather persists, but there are several things you can do to
protect your family and to reduce your risk of becoming infected. If possible, avoid outdoor activities
from dusk until dawn, when mosquitoes are most active. If you will be outdoors during this time, wear long sleeves and pants, and be sure to use an insect repellant containing DEET (N,N-diethyl-m-toluamide). Continue to protect yourself until after the first hard freeze of the year. Mosquitoes breed in stagnant water and will develop in as little as four days. Eliminate areas of standing water on or near your property by disposing of old tires, cans, and containers that hold water. Clean out clogged gutters and stagnant water in bird baths or wheel barrows. Cover unused swimming pools, but be aware that water that collects on top of swimming pool covers can also serve as breeding grounds for mosquitoes. Even a small container with water in it can be a breeding site, allowing up to 1,000 mosquitoes to develop in one week.
West Nile virus is transmitted to humans when they are bitten by an infected mosquito. Most people
infected with West Nile virus show few or no symptoms, but those over the age of 50 or who have
compromised immune systems are more at risk for severe illness. Symptoms include fever, headache,
neck stiffness, nausea, vomiting and sore joints, and usually occur 3-15 days after being bitten by an
infected mosquito. More severe infections are marked by rapid onset of a high fever with head and body aches, stiff neck, muscle weakness, disorientation, tremors, encephalitis (inflammation of the brain) or
meningitis (inflammation of the tissues that cover the brain and spinal cord), convulsions and, in the
most severe cases, coma or paralysis. In some individuals, West Nile Virus can cause permanent
neurological damage or death. See your doctor immediately if you have symptoms of the disease.
